I clean my plastic lensed glasses and safety goggles as follows- rinse well under a warm tap, a few drips of washing-up liquid gently rubbed over both sides by a finger, rinse very thoroughly under warm water and leave to drip dry. I've been doing this for many years and can't find a better way.

Mick,

The material is typically polycarbonate [common trade name = Lexan].

I have found that one of the best washes for this, and any other optics, is a weak solution of "alberto balsam, tea tree tingle" Hair Shampoo … which is available very cheaply in most supermarkets.

I also use it as the wash in my ultrasonic bath.

Screwfix list 92 versions but these are almost given away with a packet of cornflakes. There are some specs style, ie lughooks for the same price. no lanyard but they can sit on your forehead and the plastic frame overlaps the 'glass' so provides some protection when placed on a clean bench.

I always use that type as it fits over my specs, but they do leave a Klingon mark on your forehead…

i use the same cleaner that is for the visor on my crash helmet it comes in a small spray bottle , available from any good motorcycle shop or e,bay designed to clean off all the dead flies and assorted road muck and dries with no smears , it also gets of oil from my old vintage bikes,i was pleased when i tried it in the workshop, so one bottle does two jobs , will

The best I have found for all my:

~ car and ATV plastic (polycarbonate) front and rear light lenses

~ ATV and motorcycle windscreens

~safety glasses, face shields and goggles

I use "Pledge" furniture polish for superb cleaning and crystal clear finish. Spray on and buff out with a microfiber cloth. Tip passed to me by a motocross enthusiast a few years back.

Hi Mick. I have been using a face mask / safety visor as suggested by David above. It works very well as my glasses are not interfered with and it is comfortable to wear. It is also very easy to pop on and off. Only downside is that I like Homer Simpson in his nuclear power station!

About £10 from Axminster HERE.

The main thing to remember is that all dust, and any potential scratchy stuff, must be washed off before any polishing is attempted. Now what I need is something that really will clean car windscreens, tried all available commercial products.

To quote from my aircraft owners manual, use plenty of water and a mild soap, rub the wet plastic with your hands, rinse, and dry off with a clean damp chamois, using it dry will cause a build up of static electricity, attracting dust, it will also cause scratches. Don't use hydrocarbons.

It is the coloured ink, they treat the paper to make it print better. Use a paper that is printed with black only ink if you can find one these days. I found an old newspaper today from 1993 before they were doing the colour print. Looks like I will be keeping it for special occasions then. Any of the really cheap dish wash liquids work well for cleaning the plastic glasses. The secret is not to rub or smear the dust/dirt/grit into the plastic and then end up scratching them. I have prescription safety glasses, and they are not too bad after 3 years. My eyes will have changed before they get too damaged and need replacing. The secret is to keep them clean, so keep your head away from coolant mist oil splashes etc, all the things that make them go grubby. I always place mine down, upside down on the bench in a clean place, so the lenses can not be scratched or the glasses can't roll over across the lens face.
